To all whom, it may OOILOGY'VL.

Be it known that I, SAMUEL F. WRAY, a citizen of the United States,residing at Elwood, in the county of Madison and State of Indiana, haveinvented certain new and useful Improvements in CornerScaffold-Brackets; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates 'to corner scaffoldbrackets.

The object of the present invention is the provision of an improved,cheapened, and

simplified corner-bracket of the class described which shall be adaptedfor quick attachment and removal and afford a stron g. and durablesupport.

The invention consists of certain novel features and combinations, aswill appear more fully hereinafter.

In the accompanying drawings, Figure 1 represents my improvedcorner-bracket in use; Fig. 2, a top perspective view with one of thebrackets removed from the angle-iron; Fig. 3, a side elevation of one ofthe brackets, and Fig. 4 a view of my improved lag-screw.

A represents the corner-post of the scaffold, and B the cross-braces.The angle-iron 1 is preferably of half-inch bar-iron and provided at itsangle with a hole 2, through which passes my improved lag-screw, to bedescribed later on. The arms of this angle-iron are provided withvertically-disposed pockets 3, formed by a bent-up strap of metal 4,suitably fastened in position. If preferred, these pockets might beformed by bending up the arm of' the an gle-iron.

The rear face of the triangular wooden bracket 5 is provided with a hook6, which is adapted to snugly fit the pocket 3 when the bracket is inposition.

My improved lag-screw for fastening the angle-iron in position consistsof threaded body or shank 7, which is provided with a longhead 8,forming, as it were, a crank,which extends at right angles to the shankand is provided with a crank-handle 9. After the angle-iron has beenplaced in position the lagscrew is inserted in the hole 2 and drivenpartially in the corner-post A. It may then be screwed into properposition by turning the crank-handle. The hooks on the brackets are nextinserted in their pockets and the crossbraces properly lashed orfastened in position on the shelves of the brackets.

Having thus described the invention, What is claimed as new is-- l.Acorner-bracket for scafiolding comprisin g the combination of an angle-iron provided with an aperture at its bend, .brackets connected tothe portions of the angle-iron, and a lag-screw adapted for reception inthe aperture of the angle-iron.

2. The combination with the corner-post of a scaffold, of a brackettherefor comprising the combination of an angle-iron, brackets connectedto the angle-iron, and a lag-screw provided with a crank and adapted tohold the angle-iron in position, substantially asdescribed.

3. A corner-bracket for scaffolding, comprising the combination of anangle-iron, bent-up metal straps connected to the portions of theangle-iron and which constitute pockets in connection therewith,brackets provided with hooks adapted for reception in the pockets, andmeans for fastening the angle-iron in position.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
